In Pictures: Priciest Private Jets

Boeing 747-8

$270 million-$280 million

Four people have already purchased the Boeing 747-8, and two of those lucky individuals ponied up the cash early enough to take possession by 2010, provided the Federal Aviation Administration certifies it for noncommercial use by then. The purchase price gets you only the basics. To outfit it with a suitably luxe interior, expect to pay $20 million more.
